I have a Riso RP3700 that has a master making problem. 95% of the masters are wrinkled on the bottom left hand corner of the drum. Does any know how to adjust. I was wondering if there is a Master reset code .
Is the screen on the Drum wrinkled? I have seen this problem and was able to change the screen with success. Also seen the Master infeed roller slip on on side slightly causing the master to enter the clamp 2 mil off, simalar issues.
